Thaum sawv ntxov ntawm Lub Ib Hlis 13, 2021, lub ntiaj teb thawj qhov kub thiab txias superconducting high-speed maglev engineering qauv thiab kev sim kab siv cov cuab yeej qub ntawm Southwest Jiaotong University tau tsim tawm hauv Chengdu, Sichuan Province, Suav.Nws yog ib qho kev ua tiav los ntawm kos hauv kev tshawb fawb ntawm qhov kub thiab txias superconducting kev kub ceev maglev project hauv Suav teb thiab peb lub teb chaws muaj cov xwm txheej rau engineering thwmsim thiab ua qauv qhia.
Thawj Case Hauv Ntiaj Teb; Tsim Ib Tug Ua Ntej
Lub commissioning ntawm high-temperature superconducting magnetic levitation technology xeem kab yog thawj nyob rau hauv lub ntiaj teb no.Nws yog ib tug neeg sawv cev ntawm Tuam Tshoj tus ntse tsim thiab tsim ib tug ua ntej nyob rau hauv lub tshav pob ntawm high-kub superconductivity.
Lub high-temperature superconducting maglev tsheb ciav hlau tshuab muaj qhov zoo ntawm tsis muaj qhov chaw ruaj khov, qauv yooj yim, txuag hluav taws xob, tsis muaj tshuaj lom neeg thiab suab nrov, kev nyab xeeb thiab kev nplij siab, thiab cov nqi khiav lag luam tsawg. ntau yam ceev ceev, tshwj xeeb tshaj yog haum rau kev khiav hauj lwm ntawm high-speed thiab ultra-high-speed kab;Lub tshuab no yog lub tshuab hluav taws xob kub kub superconducting maglev tsheb ciav hlau tshuab nrog nws tus kheej ncua kev kawm, tus kheej taw qhia, thiab nws tus kheej-stabilizing yam ntxwv.Nws yog tus qauv tshiab kev tsheb ciav hlau txoj kev tsheb thauj mus los ntsib kev txhim kho yav tom ntej thiab dav daim ntawv thov kev cia siab.Lub tshuab yog thawj zaug yuav tsum tau tsim nyob rau hauv ib puag ncig atmospheric, thiab kev khiav hauj lwm ceev lub hom phiaj tus nqi yog ntau tshaj 600 km / h, uas yuav tsum tau tsim ib tug tshiab. sau tseg rau av tsheb khiav ceev hauv ib puag ncig atmospheric.
Cov kauj ruam tom ntej yog los ua ke rau yav tom ntej lub tshuab nqus tsev vacuum pipeline technology los tsim kom muaj kev thauj mus los zoo uas ua rau muaj qhov tsis sib xws hauv kev thauj mus los hauv av thiab kev thauj mus los hauv huab cua ceev, uas yuav ua rau lub hauv paus rau kev ua haujlwm ntev hauv kev nrawm dua 1000 km / h, yog li tsim kom muaj lub hauv paus rau kev ua haujlwm ntev ntev hauv kev nrawm dua tus qauv tshiab ntawm kev thauj mus los hauv av.Kev saib mus tom ntej thiab cuam tshuam kev hloov pauv hauv kev tsim kho tsheb ciav hlau.

Sib nqus Levitation Technology
Tam sim no, muaj peb "super magnetic levitation" thev naus laus zis hauv ntiaj teb.
Electromagnetic levitation technology nyob rau hauv lub teb chaws Yelemees:
Lub hauv paus ntsiab lus ntawm electromagnetic yog siv los paub txog cov levitation ntawm lub tsheb ciav hlau thiab txoj kev khiav.Tam sim no, lub tsheb ciav hlau Shanghai maglev, lub tsheb ciav hlau maglev tab tom tsim kho hauv Changsha thiab Beijing yog tag nrho hauv lub tsheb ciav hlau no.
Nyiv tus kub-kub superconducting sib nqus levitation tshuab:
Siv cov khoom siv superconducting ntawm qee yam khoom ntawm qhov kub thiab txias (txias rau -269 ° C nrog kua helium) kom lub tsheb ciav hlau levitate, xws li Shinkansen maglev kab hauv Nyiv.
Tuam Tshoj high-temperature superconducting magnetic levitation technology:
Lub hauv paus ntsiab lus yog qhov pib zoo ib yam li qhov ntsuas kub tsis tshua muaj superconductivity, tab sis nws qhov ua haujlwm kub yog -196 ° C.
Hauv kev sim yav dhau los, qhov sib nqus levitation hauv peb lub tebchaws tuaj yeem tsis tsuas yog raug tshem tawm tab sis kuj raug tshem tawm.

Qhov zoo ntawm High Temperature Superconducting Maglev Tsheb ciav hlau
Kev txuag hluav taws xob:Levitation thiab kev taw qhia tsis tas yuav tsum muaj kev tswj hwm lossis lub zog ntawm lub tsheb, thiab lub kaw lus yog qhov yooj yim.Kev ncua thiab kev taw qhia tsuas yog yuav tsum tau ua kom txias nrog cov kua nitrogen pheej yig (77 K), thiab 78% ntawm huab cua yog nitrogen.
Kev tiv thaiv ib puag ncig:Qhov kub-kub superconducting sib nqus levitation tuaj yeem ua levitation statically, tsis muaj suab nrov;cov hlau nplaum mus tas li tsim ib qho chaw sib nqus zoo li qub, thiab qhov chaw sib nqus hauv qhov chaw uas cov neeg caij tsheb kov yog xoom, thiab tsis muaj kuab paug electromagnetic.
Kev kub ceev:Lub levitation qhov siab (10 ~ 30 hli) tuaj yeem tsim raws li qhov xav tau, thiab nws tuaj yeem siv los khiav ntawm qhov zoo li qub mus rau qis, nruab nrab, kev kub ceev thiab ultra-siab ceev.Piv nrog rau lwm yam sib nqus levitation technologies, nws yog qhov tsim nyog rau kev thauj mus los ntawm lub tshuab nqus tsev vacuum (ntau tshaj 1000 km / h).
Kev nyab xeeb:Lub zog levitation nce exponentially nrog qhov txo qis ntawm qhov siab levitation, thiab kev nyab xeeb ntawm kev ua haujlwm tuaj yeem ua kom ntseeg tau yam tsis muaj kev tswj hwm ntawm txoj kab ntsug.Txoj kev taw qhia tus kheej ruaj khov kuj tuaj yeem ua kom muaj kev nyab xeeb ntawm kev ua haujlwm hauv kab rov tav.
Kev nplij siab:Qhov tshwj xeeb "pinning force" ntawm high-temperature superconductor ua rau lub tsheb lub cev ruaj khov nce thiab nqis, uas yog ib qho kev ruaj ntseg uas nyuaj rau txhua lub tsheb kom ua tiav.Dab tsi cov neeg caij tsheb tau ntsib thaum caij yog "kev xav tsis muaj kev xav".
Tus nqi ua haujlwm qis:Piv nrog German tas li-conductivity sib nqus levitation tsheb thiab Japanese low-temperature superconducting magnetic levitation tsheb siv kua helium, nws muaj qhov zoo ntawm lub teeb yuag, qauv yooj yim, thiab tsis tshua muaj kev tsim khoom thiab cov nqi khiav lag luam.
Kev tshawb fawb thiab thev naus laus zis ntawm Liquid Nitrogen
Vim yog cov yam ntxwv ntawm superconductors, lub superconductor yuav tsum tau muab tso rau hauv cov kua nitrogen ib puag ncig ntawm -196 ℃ thaum ua haujlwm.
High-temperature superconducting magnetic levitation yog ib lub tshuab uas siv cov magnetic flux pinning cov yam ntxwv ntawm high-temperature superconducting bulk cov ntaub ntawv kom ua tiav ruaj khov levitation yam tsis muaj active tswj.
